Elkhart Products COU-12 Copper Coupling 1/2 Inch C X C

Product Description

The ELKHART PRODUCTS COU-12 is a 1/2-inch copper coupling with stop, designed for sweat-solder connections in residential and commercial plumbing systems. Part of the KLEENFIT product line, this fitting arrives pre-cleaned and bagged to meet cleanliness requirements for solder-ready installation. The integrated stop prevents pipe over-insertion, ensuring consistent joint depth on every connection. At 0.021 pounds and compact dimensions, it is a standard-duty fitting suited for copper tube runs where reliable, leak-free joints are required. Licensed plumbers and pipefitters install this type of fitting daily on potable water, hydronic heating, and general-purpose copper piping systems.

This coupling is intended for use in 1/2-inch copper tubing applications using a cup-to-cup (C x C) solder joint configuration. The KLEENFIT pre-cleaning process reduces prep time on the job by delivering a fitting that is ready to flux and sweat without additional cleaning steps. It is well suited for new rough-in work, repair, and retrofit projects in residential and light commercial plumbing.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC).

Clean and flux all mating surfaces per standard sweat-soldering practice, even with KLEENFIT pre-cleaned fittings, if local code or conditions require it.
